Good morning,

We have a server that was previously running RPC over HTTP and working until about a week ago.  It was a standard setup using SSL running in Exchange 2003 on a Windows 2003 Standard server (sp2)

I'm trying to troubleshoot whats going on with this and I'm not to familar with RPC over HTTP.  Here's what I have so far...  

- Checked the Virtual Directories under IIS, RPC wasn't there, but RPCwithCert was
- Added a new RPC Virtual Directory and pointed it to the RPCProxy.dll file
(I can now go to FQDN/rpc and it will ask me for a user/pass but any combo doesn't work)
- I can still go to both (http and https) FQDN and authenticate via OWA

So not really sure where to go from here.  When I try to configure the client for testing (with same setup that previously worked) I just keep getting the same Authentication error.  Sometimes it acts like it is going to work but freezes my Outlook client up which is external by the way.  

I'm just coming into this setup, I was not the one who orginally installed and configured RPC over HTTP.  

Any ideas would be greatly appreciated.  

Thank you.
